Your Pond Throughout the Seasons: some advice

A lake or pond without aeration or water treatment will eventually become a place where water collects and where water quality problems appear over the years. How to avoid pond problems or reverse an existing situation so you can enjoy your pond to the fullest? Read on…Spring runoff in the watershed causes nutrients and sediments to flow into the water, especially in those ponds built on waterways or ditches. Spring runoff consists of rain and snowmelt, organic waste and fine particles that will eventually accumulate at the bottom of the pond. Without aeration or circulation these organic sediments accumulate and slowly decompose into sludge, releasing more nutrients over time. In early Spring try adding a pre-conditioner beneficial natural bacteria, such as Bacterius PS to help quickly decompose accumulations of leaves, sediment and other organic waste from the previous fall.

Without aeration or the addition of natural beneficial bacterial treatments to your pond, you risk the formation of dreaded algal blooms; every pond owner’s nightmare. Encouraged by the growing presence of nutrients combined with the heat and light, algae have all the proper conditions to bloom. Often early in the season non-aerated ponds begin to show the signs of an algal bloom along the water’s edge. The phytoplankton gives a typical green colour to the water which limits penetration of light rays in the pond. An abundance of phytoplankton causes an organic layer to form at the bottom of the pond consisting of dead phytoplankton cells. This organic layer quickly consumes the oxygen needed for the survival of other organisms including fish. The depletion of oxygen also results in the release of nutrients such as phosphorous which act to feed the growth of an even larger algal bloom. Another effect relating to lack of oxygen is the formation of hydrogen sulphide. This potentially dangerous gas gives off the odour of rotten eggs and is an indicator that your water lacks oxygen. With the formation of the thermocline (the thermocline is the area of rapid thermal transition between the generally warmer and oxygenated surface waters and generally colder and deep anoxic -lacking oxygen- waters), the layer of organic sediments found on the pond floor begins to run out of oxygen and worsens the nutrient loading in the water column (see this animation on the effects of aeration in a dugout).

The installation of an aeration system will maintain a constant flow of oxygen which is the first defense against the growth of algae and phytoplankton. Adding an aquatic pond dye to the water also helps reduce light penetration into the water column, further reducing productivity at the depth at which aquatic plants can grow.


The most difficult management period at the pond begins at the onset of long hot days of summer, when filamentous algae and phytoplankton consume the latest available nutrients in the pond and eventually die and sink to the bottom. Cyanobacteria or blue- green algae can take over; they need a presence of phosphorus and heat to start their cycles. Applying an algeacide such as Polydex is an effective treatment against algae growth. In the correct dosage, it can be used safely without risk to plants or fish. Copper ions in low dosage are also a stimulant for beneficial bacteria. At all times avoid the use of pool algaecides in your pond because they are formulated very differently and will affect the beneficial bacteria that work to maintain balance in your pond.

Without the important presence of lake bottom aeration where the rising bubbles from the aeration system’s diffusers release oxygen in the first few feet of water, nutrients (nitrogen, phosphorus) and metals (magnesium, iron) in the organic sediments become dissolved and will be released in the water column. As these nutrients are released, particularly later in the summer as water temperatures rise, they become available for more noxious algae blooms associated with cyanobacteria (blue-green algae) and string or filamentous algae. Aeration of the entire water column is therefore essential to maintain a good balance in your pond. To control aquatic plants, there is no quick fix; consider using the benthic barrier Aquascreen or tools such as aquatic rakes and cutters. Over the long run, applications of beneficial bacteria and oxygen will help remove deep sediment that has become habitat for some aquatic weeds.

Lake bottom aeration (not surface aeration) also can help reduce coliforms and E-coli bacteria as the mixing of the water column exposes these microscopic bacteria to UV rays, reducing their numbers. This method of lake bottom aeration is now recognized by MAPAQ (Ministry of Agriculture, Fisheries and Food of Quebec) for vegetable producers. These farmers are eligible for grants under the Prime-Vert program, for the purchase of our aeration systems that have been certified by government experts for this purpose.
